Abstract : in this article, starting from solute s transport a nd diffusion equati on, aiming at the saturation state of liquid in homogeneous soil of impermeable stratum and on the condition that lots of saturated solute ( e. g. nutriment ) on t op of the soil maintain diffusion, a strict mathematical deduction is carried ou t, and the analytical solution of solute s concentration distribution in homogeneous s o il is given
文摘:從溶質輸移擴散方程出發，針對強透水層上均質土壤的液體飽和狀態，在頂層含有大量飽和溶質（如養分等）維持著滲透擴散的條件下，進行嚴密的數學推證，給出均質土壤中溶質濃度分佈的解析解。
